This water-resistant roll-top backpack has a storage capacity of up to 43 litres. Besides the main storage compartment, the backpack provides 18 additional pockets, including a laptop sleeve and a detachable waist belt. The patented T-Aero system creates space between the bag and the wearer’s back, providing continuous ventilation. Loose strap ends are rolled up and attached to the straps with Velcro fasteners. Thanks to reflective elements on three sides of the bag, which reflect 300 times more light than white fabric, the backpack is highly visible even in the dark.
